Purpose : Tissue Doppler imaging(TDI) is recently being used for assessement of regional ventricular function in adults. However, data in neonates have not been established yet. The aim of this study is to establish reference values of TDI velocities and to investigate the effect of other factors on TDI velocites in the neonatal population.
Methods : Forty eight healthy neonates with... |

Purpose : We evaluated allele frequencies and distribution of surfactant protein A2(SP-A2) in Korean neonates in order to estimate the prevalence of RDS, to find out new SP-A alleles, and to establish new steroid therapy.
Methods : Genomic DNA was extracted from 71 neonates and served as a template in PCR for genotype analysis. SP-A gene-specific amplications and gene-specific allele determinations... |
